Application filed January 12, 1920. Serial No. 351,076.

To all whom it may concern:

Be it known that I. Annizn'r l-l. Barns. a citizen of the United States,residing at Cleveland lleigh-ts in the county of Guyahoga and State ofOhio. have invented a certain new and useful Improvement in EmbossingMachines. of 'which the following is a full, clear, and exactdescription, reference being had to the accompanying drawin s. lhisinvention relates to a machine actuated by a keyboard and adapted toemboss letter and numeral characters on a strip of" material adapted foruse in an addressing machine. The machine is of that type wherein thereare a pair of cooperating rotary die carriers. the position of which isdependent upon the keyactuated, the particular dies thus placed beingthen caused to impress an interposed strip of material.

Reference is made to the followingpatents for a fuller showing anddescription, of

p'arts shown herein incidental to the die carrier, the dies and theirimmediate operating mechanism. namel'v, Patent #582,178, May

The present invention is concerned with means for enabling theemhossing'to be effected in both upper and lower case charactel-s, thepatents mentioned operating only with single case characters. Iaccomplish the desired result without unduly increasing the size of the.machine, or the centrifugal force of the rotating parts, by means of ashift mechanism which enables the same general operating mechanism toactuate different sets of characters as desired.

Invention includes the shift feature broadly. and also a preferred wayof carrying it out comprising so-arranging the dies that they may havea. shiftable movement in addition to their rotary-positioning and is anenlarged sectional side elevation of. the

Fig. 1'4" is a cross section ofthe shiftaloie pivot biock.

I will first describe the machine shown in Fig. 1. This machine has aframe 1 in which are joiirnaled a pair of paralleishatts 2 and 3. cactiot which has on it adislviilze die-car The die-s hereinafter describedof one ie carrier are male dies. andthoseoi theothcr die carrier are 5e.ies and substantially complementary to. The shatts 2 and.3 are gearedtoger by years 7 and 8 of the same size. Ca a ml with the shaft 3 is adriving pnlle 11 having; a conical "friction surface. is against whichhear clutch shoes 13 connected with the shatt 3 in a m anner to behereinatter described. it thus results thatthe pulley may continuouslyrotate the two die carriers at the same speed but inopposite directions.

On the shaft 3 is a stop arm 20. At the rear of. this stop arm andplaced equidisa-portion of the removable ring tantly about the axis ofthe shaft 3 are I series offs'lidable stop pins 21 guided in a suitableframe support 22 and each connectedwith one of the correspondingfinger-keys 25: When a finger-key s depressed the corr sponding pinis'projected into the path of the stop arm, whereby the two shafts arestopped with'coxnplementary die blocks tacthrough slots 65 in thecarrier-and engage notches 78 in the die blocks.

A convenient way to construct the carrier is to make the radial groovespartly in the portion 60, 61 connected with the shaft and partly in aring 56 secured thereto. The studs may be pins resting in notches 67inthe meeting faces of these two members of .projccting into thepassages from opposite sides, slots through the rear wall of themen'iber to-the passageways. The details of this die carrier are clearlyshownin Figs. 7. 9 and 10.

Surrounding each die carrier 5 is a sleeve 100 having slots 101 throughwhich the dies project. This sleeve has a hub 103' em bracing the shaft.In the outer face of this y It is convenient hub is a radial groove 103.This groovefurnishes means whereby the sleeve may be engaged to beshifted longitudinally and thus swing all of the dies into one activeposition or the other. Irrespective of which' position the dies have,they are operable by the plunger 35 or 36.

The mechanism'i'or engagingand longitudinally n'ioving the sleeves 100to shift the dies is best shown'in Figa4 and 11. As there shown itconsists-of a yoke 110 slidably mounted on stationary guiding studs 1.11and having iorlcs 112 and 113 engaging the grooves 103 of the sleeves.This yoke has pins 115 towhich is pivoted the upper arm of the rock arm1.1% on the rock shaft 117. A substantially horizontal arm 118 on thisrock shaftis connected by a link 1 19 with th shift lever 120. Asuitable spring 123 tend to elevate this shift lever and thereby ma:tion, which is preferably that where the lower case characters areactive. When the key is depressed it pulls downwardly on the link 119and swings the bell crank to shift the yoke and the two sleeves 100'renrwardly' to swing all the dies to bring their other set ofcharacters, preferably the upper case,

intoactive position.

l to have suitable means to hold the shift lever depressed. For thispurpose I have shown a catch 121 pivoted to the machine frame andhavingan eccentric or m foot 122 adapted to extend across and c1" (wethe shift lever "nd hold it der pressed, this shlft lever being gmded bya --block s 4131 sliding radially a both sleeves in one extreme posiframe slot 123. This catch has an arm which is normally held in eitherextreme position by means of its engagement with a leaf spring 126carried by the frame and having a slight intermediate hump which thelever must pass across in moving from one extreme position to the other.This catch-mechanism is shown in Figs. 12 and 13.

It will be seen that by my invention I have adapted an embossing machineof the type mentioned, to an operation with two sets of characterswithout adding much mechanism to the machine and without materiallyincreasing its size and weight and without troublesome increase in thecentrifugal force of the rotating die carriers.

broader aspects it comes within the scope of this invention.

Another means for accomplishing the result, and intended to be coveredbroadly by claims in this patent, consists as shown in Figs. 14 to 16 inusing for the lower case characters, a rotary wheel-130 having die only,substan? tially as shown in. Patent 883,400 issued March 31, 1908, to R.Grieser for a die car-. rier, and forming the upper case-characters onspring fingers 132 which extend longi-' tudin'ally in a cylindricalcourse and may be carried by a suitable disk-like head as shown inPatent 5559,21 1 granted July 9,

its

1907, to R. v(irieser fora die carrier or may be made longitudinallyslitting a spring metal sleeve 133 as shown also in patents to. Craneand Alling, already mentioned. In either case the spring fingers arearranged in the form of a cupjo'r ring of slightly larger diameter thanthe carrier for the small-letters, which cup or ring may be shiftedlongitudinally as a unit over the small-letter carrier, so that when thesmallletter dies are plunged outwardly they will engage the innersurface of the spring fingers and the embossing. cient clearance. isprovided between the male and female lower case carriers to provide forthe surmounting of the spring fingers, and

stroke is increased when the fingers are not active to com.- Thisincrease in stroke the plunging surmounting pensate therefor.
